Question Is my PSU faulty?

[ImmortalSoldier]

Hello, I recently bought a psu tester and it just keeps beeping. All of the numbers seem to be ok, but where it says PG it looks low to me at 130 ms and blinks and beeps. What does the PG mean and does it mean its faulty? I tried it with another PSU (older working model) and it doesn't beep at all.

This is an MSI 850W, the newer ATX 3.0 power supplies.

Yeah it seems to be on the low side but still within acceptable range (less than 100ms would be abnormal). Test it multiple times and see if the value drops closer to or below 100ms. If not, I think you should be fine.
